Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is the continuation of the international patent application No. PCT/CN2022/1168418, filed on Sep. 1,2022, and claims the priority benefit of Chinese Patent Application No. 202111054068.4, filed on Sep. 9,2021, the full disclosure of which is incorporated herein by reference.

BACKGROUND

TECHNICAL FIELD

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a transmission scheme and device for flexible transmission direction configurations in wireless communications.

RELATED ART

Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 session to standardize the NR. It was decided at the 3GPP RAN #86 Plenary that the Study Item (SI) and the Work Item (WI) of NR Rel-17 should be started, and the SI and WI of NR Rel-18 are expected to be proposed at the 3GPP RAN #94e plenary.

Enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC) and massive Machine Type Communications (mMTC) are three major application scenarios in New Radio (NR) technology. In the NR Rel-16 system, a major difference compared to the LTE (i.e., Long-Term Evolution) and LTE-A (i.e., Enhanced Long-Term Evolution) frame structures is that the symbols in a slot can be configured as Downlink, Uplink, or Flexible. For a symbol configured as “Flexible”, the terminal receives downlink transmissions on that symbol, and that symbol can also be used for uplink scheduling. The above approach is more flexible than LTE and LTE-A systems.

SUMMARY

In the existing NR system, spectrum resources are statically divided into FDD spectrum and TDD spectrum. As for TDD spectrum, both the base station and the UE work in Half Duplex Mode. Such Half Duplex Mode avoids self-interference and reduces the influence of Cross Link interference, but it also brings about a reduction of resource utilization ratio and a longer delay. In view of these problems, to support flexible duplex mode or variable link directions (Uplink, or Downlink, or Flexible ones) on the TDD spectrum or the FDD spectrum becomes a possible solution.

As the uplink and downlink configurations in the system become more flexible, especially for base stations, downlink and uplink transmissions are performed simultaneously on different bands in the same time slot. However, in existing Vehicle-to-Everything (V2X) services, the base station tends to allocate a portion of the uplink resources for the transmission of V2X services. If there is overlapping resource between uplink resources used for V2X transmission and frequency-domain resources configured as “flexible”, or if there is cross-link interference between them, when the resources configured as “flexible” are used for downlink transmission in the cellular network, the so-called downlink transmission will cause interference to the reception of V2X signals, and corresponding solutions need to be considered.

To address the issue of configuration of the link direction in cases supporting Flexible Duplex Mode, the present application provides a solution. It should be noted that in the description of the present application, the flexible duplex mode is only used as a typical application scenario or example; the present application is equally applicable to other scenarios facing similar problems (e.g., scenarios in which there is a change in the link direction or other scenarios supporting multi-stage configuration of the transmission direction or scenarios with a more capable base station or user equipment, such as scenarios supporting full-duplex on the same frequency, or for different application scenarios, such as eMBB and URLLC, where similar technical results can be achieved). Additionally, the adoption of a unified solution for various scenarios, including but not limited to eMBB and URLLC scenarios, contributes to the reduction of hardcore complexity and costs. In the case of no conflict, the embodiments of a first node and the characteristics in the embodiments may be applied to a second node, and vice versa. Particularly, for interpretations of the terminology, nouns, functions and variables (unless otherwise specified) in the present application, refer to definitions given in TS36 series, TS38 series and TS37 series of 3GPP specifications.

The present application provides a method in a first node for wireless communications, comprising:

• • receiving a first information block, the first information block indicating a first value; and
  • receiving a first signal in a first time-frequency resource set, a transmit power value of the first signal being a first power value;
  • herein, a time-domain resource occupied by the first time-frequency resource set is a first time unit, and a frequency-domain resource occupied by the first time-frequency resource set belongs to a first sub-band; at least one of a slot format corresponding to the first time unit or a relation of the first sub-band and a target sub-band is used to determine whether the first value is used to determine the first power value; configuration information for the target sub-band is used to at least determine a slot format for the target sub-band.

In one embodiment, a technical feature of the above method is that when the slot format corresponding to the first time unit is flexible, the transmit power value of downlink signals sent in the first time unit will be reduced by the first value, thereby avoiding that when the first time unit is configured as a V2X resource for other terminals, the downlink signals sent in the first time unit will cause interference to the V2X reception of other terminals.

In one embodiment, another technical feature of the above method is that when there is an overlap between the first sub-band and the target sub-band and the target sub-band supports a flexible duplex mode, the transmit power value of downlink signals sent in the first time unit will be reduced by the first value, thereby avoiding that when the first time unit is configured as a V2X resource for other terminals, the downlink signals sent in the first time unit will interfere with the V2X reception of the other terminals.

According to one aspect of the present application, comprising:

In one embodiment, a technical feature of the above method is that the above operation of reducing the transmit power value by means of the first value is carried out only in the first signal, i.e., for other signals of the same type, such as the second signal, the transmission is still carried out by means of transmitting without reduction of the power value, in order to ensure downlink coverage.

According to one aspect of the present application, comprising:

• • receiving a second information block;
  • herein, the second information block is used to indicate the configuration information for the target sub-band, the slot format for the target sub-band includes the target sub-band supporting transmissions in multiple links, or the slot format for the target sub-band includes symbols in the target sub-band supporting a flexible or variable duplex slot format.

In one embodiment, a technical feature of the above method is that the slot format of the target sub-band is configured by means of the second information block, i.e., the target sub-band is capable of supporting a flexible duplex mode, and thus the target sub-band can be configured for V2X transmission.

According to one aspect of the present application, comprising:

• • receiving a third information block;
  • herein, the third information block is used to indicate the slot format corresponding to the first time unit.

According to one aspect of the present application, the slot format corresponding to the first time unit is used to determine whether the first value is used to determine the first power value; when the slot format corresponding to the first time unit supports flexible or variable duplex, the first value is used to determine the first power value; when the slot format corresponding to the first time unit does not support flexible or variable duplex, the first value is not used to determine the first power value.

According to one aspect of the present application, the relation of the first sub-band and the target sub-band is used to determine whether the first value is used to determine the first power value; a frequency-domain location of the target sub-band is used to determine a second sub-band; when there is an overlap between the first sub-band and the second sub-band, the first value is used to determine the first power value; when there is no overlap between the first sub-band and the second sub-band, the first value is not used to determine the first power value.

According to one aspect of the present application, comprising:

• • receiving a synchronization signal;
  • receiving a third signal in a third time-frequency resource set; and
  • receiving a fourth signal in a fourth time-frequency resource set;
  • herein, a frequency-domain resource occupied by the third time-frequency resource set and a frequency-domain resource occupied by the fourth time-frequency resource set both belong the first sub-band; a time-domain resource occupied by the third time-frequency resource set is the first time unit, while a time-domain resource occupied by the fourth time-frequency resource set is the second time unit; each of the first signal and the second signal comprises a channel state information reference signal (CSI-RS), and each of a physical layer channel occupied by the third signal and a physical layer channel occupied by the fourth signal comprises a physical downlink shared channel (PDSCH); an EPRE of the synchronization signal, a first offset value and the first value are used to determine an EPRE of the first signal; the EPRE of the synchronization signal and the first offset value are used to determine an EPRE of the second signal, and the first value is not used to determine the EPRE of the second signal; the EPRE of the first signal and a second offset value are used to determine an EPRE of the third signal, and the EPRE of the second signal and the second offset value are used to determine an EPRE of the fourth signal; a radio resource control(RRC) signaling is used to determine the first offset value and the second offset value.

In one embodiment, a technical feature of the above method is that when the first signal and the second signal are both CSI-RS (i.e., Channel-State Information Reference Signals) and the third signal and the fourth signal are PDSCHs (i.e., Physical Downlink Shared Channels), the relationship between the EPRE (i.e., Energy Per Resource Element) of the existing PDSCH and the EPRE of the CSI-RS remains unchanged, namely, when the CSI-RS reduces the transmit power by the first value, the PDSCH located in the same slot or symbol also reduces the transmit power by the first value; when the CSI-RS does not reduce the transmit power by the first value, the PDSCH located in the same slot or symbol does not need to reduce the transmit power either.

In one embodiment, a technical feature of the above method is that when the first node calculates CSI (i.e., Channel-State Information) by means of the first signal, the transmit power value which is suppressed by means of the first value should not be calculated for the receive power value of the first signal, namely., the receive power value of the first signal used for calculating the CSI should be ramped up by the power value corresponding to the first value compared with the actual receive power value.

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a control plane 300 between a first communication node (UE, gNB or, RSU in V2X) and a second communication node (gNB, UE, or RSU in V2X) is represented by three layers, which are L1, L2 and L3. The layer 1 (L1) is the lowest layer which performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between a first communication node and a second communication node via the PHY 301. The L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All these sublayers terminate at the second communication nodes. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting packets and also support for inter-cell handover of the second communication node between first communication nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel.

The MAC sublayer 302 is also in charge of HARQ operation. In the control plane 300, the Radio Resouce Control (RRC) sublayer 306 in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second communication node and the first communication node.

The L2layer 355 in the user plane 350 also comprises a Service Data Adaptation Protocol (SDAP) sublayer 356, which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversified traffics.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to the present application, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication device 450 and a second communication device 410 in communication with each other in an access network.

The first communication device 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

The second communication device 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, a higher layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides functions of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation of the first communication device 450 based on various priorities. The controller/processor 475 is also in charge of a retransmission of a lost packet and a signaling to the first communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (i.e., PHY). The transmitting processor 416 performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device 410 side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream, which is later provided to different antennas 420.

In a transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver 454. The receiving processor 456 converts the processed baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any first communication device 450-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted by the second communication device 410 on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 provides functions of the L2 layer. The controller/processor 459 can be associated with a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer. Or various control signals can be provided to the L3 for processing.

In a transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the second communication device 410 described in the transmission from the second communication node 410 to the first communication node 450, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for a retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor 468 then modulates generated spatial streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457, are provided from the transmitter 454 to each antenna 452. Each transmitter 454 firstly converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the function of the second communication device 410 is similar to the receiving function of the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with a memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the first communication device (UE) 450.
